High Compression and DD


How is it? Is there any difference at all?

Hes saying the compression in the engine keeps the car from moving when parked. Which is true... But not enough to make a difference i dont think :p i use e-brake just in case.

I guess it makes sense but I really thought just leaving it in gear was enough. Granted I always use my e-brake anyway and never really park on hills that I can think of.

Still wondering if that really is true. Absolutely never heard of that.

lol Yeah its true. You dont need an ebrake if its in gear. On a hill its not the smartest thing to do though. Cause like he said it can eventually roll sometimes. I heard it jump started a car once too lol. But i think thats 1 in a million.

Yes its true because with high compression its harder to turn over the engine than with a lower compression. you ever try pulling the recoil on a high compression four wheeler compared to a normal one? same concept.

I wish I could move my ebrake to the left of the dead pedal like the Ford Ranger does....

I use mine everytime but I'd rather use my foot after driving my buddies Ranger. That truck was so much easier to quickly hit the brake on the way out of the car.

Minor concern though..... I'd rather do a million other things before messing with the ebrake.

high compression will burn more gas and you have to use higher octane. its less "streetable"

Please explain in detail how this is possible, raising the compression does not require the use of more fuel to make the a/f the same. Actually higher octane fuel burns at a slower rate but expands faster, running any higher than 110 octane in my car requires flow tubes on the collector flanges or it will cook the floor pan.

I am interested in where some people get their education around here at times. Articles of interest....

1. About.com: http://www.epinions.com/auto-review-6CDA-155BB277-38FF47F2-prod4?sp=ink

2. fuel octane vs power.html

I am not trying to hurt anybodies feelings, but there is way to much misinformation floating around this site.
